The Donald Trump call in the president of Taiwan and of itself, as Henry Kissinger said, hasn't created some tremendous trouble in China. But what we don't know is whether this is just posturing or whether this is a policy change.

Trump campaigned as somebody who was very skeptical of the multinational deals. He was supportive of Brexit. He was very skeptical of NATO. So what we saw of President Trump in Europe was what we saw of President Trump as a candidate.

I think you still have a problem here when you're going and you're looking not just that Trump is winning, but he's winning in a broad swath of voters. It's not just that he's got this one lane, oh, he only wins when there's low turnout, he only wins when conservatives, he only wins in these kinds of states. He wins enough across a broad array.
